As announced at the iPhone 5s launch, the Nike+ Move app is now available in the Apple App Store for free. Nike+ Move harnesses the power of the iPhone 5s’ M7 coprocessor. Apple describes it as a dedicated sidekick chip that analyzes the movement of the instruments without utilizing the A7 processor. The results is more efficiency with tracking physical activites, such as significantly less battery consumption, while still giving fitness apps access to the gyroscope, accelerometer, and compass. Take a gander of the features of Nike+ Move:

Nike+ Move is the simplest way to capture your every move, and motivate you to move more!

Exclusively for use with iPhone 5S, Nike+ Move uses the M7 coprocessor to convert your movement into NikeFuel, the first-ever single, universal unit for measuring all kinds of activities. No matter your age, weight or gender, the same activity earns you the same amount of NikeFuel.

Nike+ Move offers insight into when you move, how you move and where you move - and lets you challenge your friends to see who moves more.
